Remote-control nestbox (bird) trap design calls for one 9V battery (pack with switch) boosted to 12V with MT3608 module to power 12V 433Mhz RF remote receiver, which is connected to a ZEY1-0530 solenoid (specs: 12V DC 1A 10mm push pull) that holds the tiny trap door open until remote triggers solenoid plunger to retract releasing door to spring shut.
Solenoid plunger retracts when RF remote transmitter button is pushed, but is too weak to retract when holding the trap door open (sheet metal trap door size/gauge and .4mm torsion spring are to design specs).
The design also called for removing the RF remote transmitter battery and connecting another 9V battery, boosted to 12V with MT3608 module (just like the one connected to the receiver) to the transmitter battery terminals. I didn't do this bc when I tested the transmitter with its own (CR2) battery, it worked to power the receiver, triggering the solenoid to retract.
As mentioned however, once plunger was placed over edge of trap door, the solenoid was too weak to retract the plunger, even though tension from .4mm torsion spring is extremely light.
I know nothing about electronics. I wondered about the transmitter design, but assumed the extra power supply had to do with distance or something. I mean, I didn't think the transmitter's power supply would be related to the amount of power being delivered to the solenoid.
Could it be that the design called for increasing the transmitter's power supply to 12V (the 9V battery boosted to 12V, in place of the CR2 battery) because that somehow increases or helps sustain the amount of current the receiver's power supply is able to deliver to the solenoid?
